Abstract
An MRI system acquires a susceptibility-weighted image by acquiring a first RF echo signal in a first echo time for providing an image exclusive of susceptibility-weighting and acquiring a second RF echo signal in a second echo time longer than the first echo time for providing an image including susceptibility-weighting. A compensation gradient field is applied for compensating for field inhomogeneity and in response, a third RF echo signal is acquired in a third echo time longer than the second echo time. First, second and third images are generated in response to data derived from the first, second and third RF echo signals respectively and data of the first, second and third images is combined to provide image data representing an image compensating for magnetic resonance signal attenuation in the second image.
